Arthur Schopenhauer

"Life is suffering, and only the renunciation of will brings freedom from suffering."

"Wisdom is the art of reducing suffering."

"Man is what he thinks and what he desires."

"Happiness is always fleeting; it is only a brief moment between two sufferings."

"A person can make their existence easier by renouncing passions."

"Will is the foundation of all existence."

"Thoughts shape our perception of the world, and the clearer they are, the less suffering we experience."

"It is better to be wise than happy, for happiness cannot be permanent."

"Philosophy is an attempt to clarify the essence of things."

"The ideas created by man often do not correspond to his real life."
